Balcony or terrace gardeners are mostly plant and flower lovers who do not have their own garden. And yet they develop great and admirable gardening skills to turn their few square meters in front of the apartment into a blooming gem. Plants, shrubs and shrubs thrive there that grow equally in the garden. A number of houseplants mix among them.

In the open air, the rose marshmallow (Hibiscus rosa-sinensis) also feels in good hands in summer. The main reason that this develops well over many years in the pot or in the bucket is that it is repotted from time to time. Instructions for repotting can be found here step by step.

Repot the hibiscus before going into summer

It is time to think about transplanting the room hibiscus when the first root tips can be seen from the drain holes on the bottom of the pot.
The best time for this is spring, when the growth spurt of the plant begins. That can vary from region to region. Observations have shown that in the south of Germany this growth spurt can already start in March, while in the north it is a long time coming.

For example, the forsythia (gold bell) could be the right time to repot.

Sinnvoll Make a sensible choice of new planter for hibiscus.

  • Choose the pot to transplant the rose marshmallow wisely. A plastic planter is more recommendable than a clay pot. A clay pot absorbs the moisture when pouring. This allows minerals from the fertilizer to be absorbed by the moist wall of the pot. When watering and fertilizing, it can cause irritation for the plant. It also harms the roots if the moisture in the pot lasts too long in damp and cool summers.
  • In addition, the new pot should not be too big. If it is 1 to 2 centimeters larger than the previous one, then it is always enough. If you take a larger pot, you will need more substrate to plant. This absorbs a greater amount of moisture, much more than the plant can absorb in a short time. And that can ultimately lead to waterlogging, musty substrate and root rot.
  • For large plants, use the same pot as before. You only need to cut back the root mass.

❷ The right plant substrate

To protect the roots of the Hibiscus rosa-sinensis from possible root diseases, the plant should be placed in a special substrate. Therefore, do not use normal potting soil that has been wet for far too long. It is therefore advisable that you mix your special substrate yourself. You need:

  1. 7 parts of high quality balcony and container plant soil
  2. 2 parts of compost
  3. 7 parts perlite (available here)

Where do you get the compost from? Ask the hobby gardener in your circle of friends or colleagues if they can help you with compost. Otherwise, you can get information from your community about where a composting plant is near you and whether it is possible to buy compost from there. Another possibility is the Ga-La building. This gardening and landscaping company is represented in almost all larger towns. That can certainly help you.

❸ And off to the new pot

Ultimately, the repotting is done by yourself. Before that, you have filled the new planter with some of your own mixed substrate. Now the hibiscus can move to its new pot.

  • Hold the plant firmly and turn it upside down with the pot. Then detach the plant from the pot by tapping on the bottom of the pot.
  • When you have removed the rose marshmallow, you will find a closed root wall. It is important to loosen the root wall well. A fork can be very helpful for this. Cut long, protruding roots with sharp scissors. The hibiscus does not resent harmless root damage.
  • Now fill the gap between the root and the wall of the pot with the substrate. Then they pour their rose marshmallow on well. Place the pot on a kitchen towel. The excess water is absorbed by the cloth. So no waterlogging is caused.

by the way: If the root wall is not loosened, it can take a long time for roots to grow into the new substrate.
